 HP15C Decimal looks like a commaMessage #1 Posted by Dan on 6 Dec 2006, 10:00 p.m. Does anyone know how to get the decimal point on my HP15C to look like a decimal point. Right now it looks like a comma? Thanks

To get it back to normal (i.e., "Real" mode), type [g] [CF] [8]. (The "CF" is the blue command on the lower end of the [5] key.) - Thomas

Thanks D Many of us could have answered that -- it's probably the #1 FAQ. We all da men! The keystroke sequence for changing the radix is clever -- accessible, and intuitive once you know it, yet doesn't take a precious keyboard position on the faceplate. Most users will "set and forget" the radix unless it gets reset by some means. Earlier models (Spice, e.g. HP-34C) required the positioning of an internal jumper; later models made it a programmable command (Pioneer, e.g., HP-20S) labeled on the front. As for your other question, Flag 8 set (Complex mode) is one of the few things that are unintuitive about the HP-15C. You can remember it as one of the two "system" flags, which are the highest-numbered of the 10-member set 0-9. Flag 9 makes the display blink; it is automatically set by an overflow condition. -- KS
